PBTTPD is a donor-acceptor based high crystalline conducting polymer. It has thieno[3,4-c]pyrrole-4,6-dione (TPD), which acts as the electron-withdrawing group. Bi(dodecyl)thiophene based donor groups facilitate the polymeric unit with crystallinity and low HOMO energy levels. It shows good hole mobility and open circuit voltage (VOC).

Application

  • High-Efficiency Organic Solar Cells (OPVs)
  • Power conversion efficiency (PCE): 7.3%
  • Open circuit voltage (Voc): 0.92 V
  • Short circuit current density (Jsc): 13.1 mA/cm2
  • Fill factor (FF): 0.61
PBTTPD is majorly used as a conjugating polymer in the fabrication of organic solar cells (OSCs) and organic photovoltaic cells (OPVs). It has a power conversion efficiency (PCE) of 7.3% and a VOC of 0.92V.
